Cancelling a declaration
Asking for an invalidation
You can make an invalidation request up until the declaration is cleared.
If the declaration has not yet arrived, you will need to request invalidation.
If the declaration has arrived and is under control, the customs authority (HMRC, UK Border Force or Trading Standards) will decide if the invalidation request should be accepted.
When the control is finalised and you receive a final provisional tax or insufficient balance message is received, the invalidation request will be automatically accepted.
If you submit an amendment to an existing declaration, and an error message is displayed, it cannot be invalidated until the error has been resolved.
Asking for a withdrawal
You can send a notification to HMRC asking to withdraw a declaration up to 90 days after the earliest of the following events:
the acceptance of the declaration
a Border Force or HMRC officer instructing you to attend a physical or documentary check for the movement
